Application filed March 11,1922. Serial No. 542,913.

To all whom it may concern:

Be it known that I, HENRY RENE MAZ- ZETTI, an Italian subject, residing at Bradford, in the county of York, England, have invented certain new and useful Improvements in Circular Combs of Nobles and the like Combing Machines, of which the following is a specification.

In the circular combs of Nobles and the like combing machines, the small and large circles are each fitted with a number of rows of fiat pins and a number of rows of round pins arranged one behind the other, which, in the case of each of the small circles commence at its periphery with the fiat pins and terminate toward its inner edge with the round pins, while in the case of the large circle the fiat pins commence at its inner edge and terminate with the round pins toward its periphery.

As hitherto constructed, the fiat pins have been set in the circles at right-angles to the peripheries of the latter so as to allow the wool or fibre to be pulled straight through the spaces formed between the parallel rows of pins; and the object of this present invention is so to improve the setting of the fiat pins in both the small and large circles as to ensure a much better cleaning of the wool or fibre during the combing operation.

According to my invention, the fiat pins of both the small and large circles are arranged in rows one behind the other as before; but instead of setting these fiat pins at rightangles to the peripheries of the circles, they are set at an angle of about 35 degrees there to so as to cause all the rows of flat pins to incline in one direction or, as an alternative, the alternate rows of flat pins to incline in an opposite direction.

By setting the flat pins in the circles at an incline in the manner just described, the wool or fibre will, during its passage across the said pins, be caused to follow a zi -zag course sufiicient to ensure the removal 0 all foreign matter from the wool or fibre which in con sequence becomes effectually cleaned during the combing operation; while a further advantage of the inclined setting of the fiat pins is that, at the point of divergence between the small and large circles, the pull of the wool or fibre comes on to the said fiat pins more or less in the direction of their edge and greatest strength which keeps them in their proper relative positions.

In order that the invention may be clearly understood, I will proceed to de'scribethe same with reference to the accompanying drawings; wherein v Fig. 1 is a plan view of a portion of a combing machine, showing the two small circles and the large circle whose pins are indicated by dotted lines. Fig. 2 is an enlarged plan view of a portion of one of the small circles and a portion of the large circle, showing one form of setting of the flat pins according to my invention; while Fig. 3 is a similar view to Fig. 2, but showing another form of setting of my invention.

Referring to the drawings, 1, l are the small circles and 2 the large circle, each of which is fitted with a number of rows of flat pins 3 and a number of rows of round pins 4 arranged one behind the other; and according to my invention, instead of setting the fiat pins 3 at right-an les to the peripheries of the circles l, 1 and 2, they are set at an angle of about 35 degrees thereto so as to cause all the rows of fiat pins 3 to incline in one direction as shown in Fig. 2 or, as an alternative, the alternate rows of flat pins the fiat pins according to r 3 to incline in an opposite direction as shown at Fig. 3, whereby the wool or fibre 5 during its passage across the said pins 3 is caused to follow a zig-zag course (see Figs. 2 and 3) sufiicient to ensure the removal of all foreign matter from said wool or fibre 5 which in consequence becomes effectually cleaned during the combing operation, while in addition, the pullof the wool or fibre 5, at the point of divergence between the small and large circles 1, 2 comes on to the said flat pins 3 more or less in the direction of their edges and greatest strength which keeps them in their proper relative positions (see Figs. 2 and 3).

What I claim as my invention, and desire to secure by Letters Patent is 1. In circular combs of Nobles and the like combing machines; the combination with the small and large circles each having a number of rows of round pins, of a number of rows of fiat pins set in the circles at an angle of about 35 degrees to their peripheries so as to cause the wool or fibre, during its passage across said pins, to follow a zig-zag course sufiicient to ensure the removal of all foreign matter from said wool or fibre.

2.- In circular combs of Nobles and the like combing machines; the combination with the small and large circles each having a number of rows of round pins, of a number of rows of fiat pins set in the circles at an angle of about 35 degrees to their peripheries so that all the rows incline in one direction and cause the Wool or fibre, during its passage across said pins, to follow a zig-zag course sufficient to ensure the removal of all foreign matter from said wool or fibre.

8. In circular combs of Nobles and the like combing machines; the combination with the small and large circles each having a number of rows of round pins, of a number of roWs of fiat pins set in the circles at an angle of about 35 degrees to their peripheries so that the alternate rows incline in an opposite direction and cause the Wool or fibre, during its passage across said pins, to follow a zig-zag course sufficient to ensure the removal of all foreign matter from said wool 01 fibre.

In Witness whereof I have hereunto set my hand in the presence of two Witnesses. HENRY RENE MAZZETTI. Witnesses:
